Ke'ei is a cool place to dive. The road to Ke'ei turns right before the dump, and it is rough, so go slow. Once there, there are not many people. Me and my buddy dive off of the right set of rocks and used the step, much like Honaunau. Bail off and start diving. Lots of reef formations with big holes. Some other people I talked to after diving said it gets deep here- up to 120, but I only went to 50 feet. Great bottom with lots of fish life. Would not advise diving on a large swell day, as the entry/exit could be very challenging.
